シリコーン樹脂組成物は、低弾性かつ低応力であり、耐熱性、電気絶縁性等の信頼性に優れることから電子部品や半導体用途などに広く用いられている。 BACKGROUND ART Silicone resin compositions are widely used for electronic parts, semiconductors, and the like because of their low elasticity, low stress, and excellent reliability such as heat resistance and electrical insulation.
近年、手首や腕や頭に装着して使用するスマートウオッチやスマートグラスに代表されるウェアラブルデバイス用材料について、様々な検討がなされており、ポリウレタン樹脂が、優れた伸縮性、強靭性を有することからウェアラブルデバイス用材料として使用され始めている(特許文献1、2)。ポリウレタン樹脂をウェアラブルデバイスの基板材料として使用し、基板に搭載された半導体素子を封止する場合、その封止材にもポリウレタン樹脂と同等の伸縮性、およびポリウレタン樹脂に対する良好な接着性が要求される。また、ポリウレタン樹脂の耐熱性の観点より硬化温度は120℃以下に限定されるため、低温で硬化することも要求される。封止材として付加硬化型シリコーン樹脂を使用した場合、ポリウレタン樹脂基板上で、付加硬化型シリコーン樹脂が十分に硬化しないという課題、あるいは硬化しても接着力が不十分であるという課題があった。 In recent years, various studies have been conducted on materials for wearable devices such as smart watches and smart glasses that are worn on the wrist, arm, or head. Polyurethane resin has excellent elasticity and toughness. Since then, it has been used as a material for wearable devices (Patent Documents 1 and 2). When polyurethane resin is used as a substrate material for wearable devices and the semiconductor element mounted on the substrate is sealed, the sealing material is also required to have the same stretchability as polyurethane resin and good adhesion to polyurethane resin. be. In addition, since the curing temperature is limited to 120° C. or less from the viewpoint of heat resistance of polyurethane resin, curing at a low temperature is also required. When an addition-curable silicone resin is used as the encapsulant, there is a problem that the addition-curable silicone resin does not fully cure on the polyurethane resin substrate, or that the adhesive strength is insufficient even after curing. .
本発明は、ウェアラブルデバイス用のウレタン樹脂基板に対して優れた接着性を有し、およびポリウレタン樹脂と同等の伸縮性を示す硬化性オルガノポリシロキサン組成物、及びその硬化物を備えたウェアラブルデバイス用半導体装置を提供することを目的とする。 The present invention provides a curable organopolysiloxane composition having excellent adhesion to a urethane resin substrate for wearable devices and exhibiting stretchability equivalent to that of polyurethane resins, and a wearable device comprising a cured product thereof. An object is to provide a semiconductor device.

The present inventors have found that a cured product exhibiting the same stretchability as that of is obtained, and have completed the present invention.
